ABSTRACT

Oil conservator is an important component of transformer assembly. Its function is to compensate the volume expansion or contraction of insulating oil due to temperature change and ensure that the body of oil filled equipment is always filled with oil. Capsule oil conservator is a sealed capsule that can bear high pressure installed in the oil conservator. The insulating oil is separated from the outside air through the capsule, and the water vapor is prevented from entering the capsule through the moisture absorber. During operation, the capsule is in the oil, and inhale or exhaust as the oil level rises or falls, so as to automatically balance the pressure inside and outside the capsule and ensure that the transformer body is always filled with insulating oil. The normal operation of capsule oil conservator can provide safety guarantee for transformer operation. With the increasing consumption of capsule oil conservator, customers often react that the actual oil level of capsule oil conservator is inconsistent with the pointer, resulting in the phenomenon of false oil level. In this paper, the intelligent pressure level gauge is successfully applied to the oil conservator and verified by simulation operation, which effectively solves the problem of false oil level.
